A difficulty level in Doom and Doom 2. Right between "Hurt Me Plenty" and "Nightmare". The best mode to play if you wanna IDDQD yourself and frag some imps. Nightmare doesn't allow cheats.

UltraViolence is fun to play on if you have beaten Unreal on "unreal" difficulty because for some reason it's harder then "unreal" is in Unreal. I think it's because the enemies respawn faster and also come in LARGE numbers.
